MILTON R. THURBER AND RICHARD B. BROGKVAY, OF SCRANTON, PA.

CAR-AXLE LU BRICATOR. v

SPECIFICATION forming part of Letters Patent No. 335,163, dated February 2, 18186.

Application {iled November 3, 1885. Serial No. 181,785. (No model.)

To all whom it may concern:

Be it known that we, MILTON R. THURBER and RICHARD B. BRooxwnY, of Scranton, in`

the county of Lackawanna and State or" Pennsylvania, have invented certain new and useful Improvements in Lubricators; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specication, and to the gures and letters of reference marked there on.

Our invention has for its object to improve the construction of lubricators for oiling the journals of railway-car axles; and it consists in acertain improved construction, which we will now proceed to describe.

In the accompanying drawings, Figure lis a side view of a canaxlelubricator constructed in accordance with our invention. Fig. 2 is a View with the casing broken away and partly in section; Fig. 3, a view of the bearing block or brass 5 Fig. 4, a view of the improved oil-conveyer.

Similar letters of reference in the several figures indicate the same parts.

A represents an ordinary car-axle, and B the bearingbox, constructed with its outer portion square, as shown, and provided at its inner or rear end with an `enlarged circular portion, B.

C is the bearing block or brass, placed in the upper part of the square portion of the box and resting upon the journal of the axle, provided with two inclined slots or grooves, lc-on'e on each side-extending from the middle of the rear end to about the middle of the lower side or bearing portion of the block.

The round portion B at the end of the box contains a recess or chamber, D, communicating with the chamber in the square portion of the box at the bottom, and the end of the brass or bearing-block C projects into it at the upper side.

E represents a wiper7 mounted upon the axle, consisting of a plate having one'or more arms, (we have shown two in the drawings,) having near their ends slight depressions or recesses e, as shown, for conveying the oil from the bottom of chamber D to the bearingblock. The plate has a perforation near its center, through which the axle extends, and one or more lugs, e', projecting inwardly, entering slots a in the axle, and securing the plate to it, so that it will revolve with the axle and within the chamber D, and will also, in revolving, pass across the end of the bearingblock C, as shown.

In the upper side of the portion B of the box is an opening provided with a hinged door, F, for the purpose of permitting the ready application and removal of the wipingplate E. In order to apply the said plate, it is necessary to withdraw the axle from the b ox and remove the bearing-block, insert the w1ping-plate through the door F into the cham ber,and then insert the axle through the perforation in the plate, causing the projections in the latter to register with the grooves in the former.

When the axle is in place, the bearing-block is put in, and the device is ready for operation.

The space beneath the bearing-block is to be lled, if desired, with wool or waste, as usual, and a small partition, G, is provided near the end of the chamber, to prevent the waste or wool from working down into the chamber D.

The operation is as follows The oil is poured into the box through the door wat the front, and collects in the bottom of the charnber D, where it is taken up in the'recesses e of the wipers as the axle revolves, and is wiped oft' into the slots or grooves c on the sides of the bearing-block and runs down said slots onto the journal of the axle, as will be readily understood. The oil dripping off the journal runs back into the chamber D, and is again wiped up into the slots in the brass, as before. Thus it will be seen that the journal will be supplied with oil as long as the car is in mo* tion, and that no oil is wasted, but it is used again and again, and positively fed to the journal until evaporated or leaked out, and is not allowed to stand and harden, as is often the case where wicking is depended upon to supply it to the journal.

The hereindescribed lubricator can be made very cheaply, and applied readily to a car, no more labor or skill being required than in the application of an ordinary car-axle box, while ICO its operation is positive, and its simple construction renders it less liable to get out of order. v

We are aware that lubricators for car-axles have been made consisting of a lifting device for dipping up the oil and pouring it into a receptacle made in the upper side of the bearing-block, which latter is provided with perforations extending through it; but the advantages of our device over such constructions as these are obvious.

We claim as our inventionl. The combination, With the axle and the v plate mounted thereon, having the arms and the depressions or recesses therein, of the Abearing-block having the grooves in its sides extending from about the middle of one end to the lower side, substantially as described.

2. The combination, With the axle having the grooves, the plate mounted thereon having the projections corresponding to the grooves in the axle, and the arms provided With the depressions or recesses in their ends, of the bearing-block having the grooves in its sides, substantially as described.

3. The combination, with the box or receptacle, and the chamber D at its end,having the opening and door in its upper side, of the axle, the removable plate or Wiper mounted on the axle, and the bearing-block provided' with the grooves inits sides, substantially as described.

4. The improved bearing-block for caraxles, having the inclined grooves on its sides extending from about the middle of one end to the lower side of the block, substantially as described.
